Saito 125a Engine Featured Engine: Saito 125a

Four stroke engines tickle the fancy of many of us because they are simply “neat.” Their sound stirs the imagination, and they carry the airplane around the sky in a more realistic fashon. But they are expensive. A lot of money can be saved by buying used RC engines, if you can find a dependable used engine. I try to make all of my used engines relaible through repair, testing, and rating so you will know what you are getting before you buy.
